PM Modi had, in a rally in the run up to the Lok Sabha polls, said, "West Bengal, under Mamata Banerjee, was known for 'triple T -- Trinamool, Tolabaazi, Tax'."

Union Minister Sushma Swaraj has cautioned West Bengal Chief Minister Mamata Banerjee against using derogatory words with respect to Prime Minister Narendra Modi. She said this in reference to the Trinamool Congress chief's remark that she wanted to give the prime minister 'a tight slap of democracy'.

"Mamataji, you crossed all limits today. You are the chief minister of a state and Modi jee is the country's prime minister. You have to deal with him only. This is why I would like to remind you of a couplet written by Bashir Badr," she tweeted, on Tuesday.

Mamata Banerjee gave the remark in connection with PM Modi dubbing TMC as 'Tolabaaz' party.

In common paralance, extortionists are referred to as 'tolabaaz'.

PM Modi had, in a rally in the run up to the Lok Sabha polls, said, "West Bengal, under Mamata Banerjee, was known for 'triple T -- Trinamool, Tolabaazi, Tax'."

To this end, Mamata, while addressing a rally in Purulia on Tuesday, said, "Money doesn't matter to me.That is why when [PM] Narendra Modi came to Bengal and accused my party of being Tolabaaz, I wanted to give him a tight slap of democracy."

This was the latest addition to the ever-growing list of barbs being exchanged between Mamata Banerjee and PM Modi.

The West Bengal chief minister had earlier said she would gift sweatmeat made of mud and mortar to PM Modi. The prime minister said it would be his 'saubhagya' to receive such a gift.

Mamata Banerjee had made this claim, in a televised interview, in response to PM Modi's declaration that she regularly sends him Bengali laddoo and two-three kurtas every year.

Prior to this, PM Modi fell on Mamata's wrong side when he claimed as many as 40 TMC MLAs were in contact with him -- leading to speculation of defection. TMC leader Derek O'Brien charged him with horse-trading.
